KC1 — Daucus carota subsp. sativus

Summary

DcKC1 (DCAR_017459) on carrot chromosome 5 encodes a voltage-sensitive potassium channel belonging to the KAT/AKT family, with outward rectifier potassium channel activity and ion transporter activity. It is associated with regulation of membrane potential, monoatomic ion homeostasis, and cellular potassium ion homeostasis, as well as upregulation of stomatal opening and downregulation of cellular defense response. The gene is linked to numerous agronomically relevant traits including yield, water use efficiency, transpiration rate, leaf necrosis tolerance, root mass density, days to flowering, and responses to alkali soil, water stress, and aluminum. It is also connected to potassium translocation, stomatal opening, reactive oxygen species response, and programmed cell death. Related genes in other species are linked to seed germination, stomatal regulation, and fatty acid beta-oxidation.
